Introduction

Anatomical and Physiological * Initial stance, grip and preparation * Travel and trunk position * Throwing Action * * Release * Overall efficiency What have I just seen? What level is the performer at? Coaching points:- Speed: This is how fast you can move your body or parts/part of your body. This is a very important factor in javelin throwing. Speed in the legs can build up momentum in the run up so that the throw can go further. Speed is also needed in the legs when pushing off the ground as this combines with strength to create power that can be applied to the javelin once thrown. ...read more.

Balance: This is the ability to maintain equilibrium. To be balanced, one must keep ones centre of gravity over its area of support. Balance is very important in throwing the javelin. Many times during the phase of throwing, much of the body's weight is on one foot then transferred to the other. This requires balance because without it, the technique may not work effectively or there is a chance of falling over. While throwing, the javelin, the centre of mass changes from the back leg (right) to the front leg (left) to get as much force on the throw possible. Coordination: This involves using the Neuro-Muscular System to produce smooth and efficient movement. ...read more.

Conclusion

There are two types: * Simple - In an activity where there is only one option available. * Choice - An activity when there is more than one option available to react to. Reaction time is not relevant to throwing the javelin. It is only relevant when a mistake is made during the technique and so you have to react to it. Power: This is a combination of speed and strength put together. Throwing the javelin requires a lot of power. Gaining momentum and actually throwing the javelin requires both speed and strength, therefore it is power. This is enabling a high force to be given to the javelin so that it can go as far as possible. *Throwing Action* Joint Joint Type Agonist Muscle Antagonist Movement Ankle Knee Hip Shoulder Elbow ...read more.

Hinge joints have ligaments mainly at the sides of the joints. These ligaments prevent lateral movement and dislocation, allowing only flexion and extension. * Gliding Joints This type of joint allows for gliding movements between flat surfaces as the surfaces slide over one another.

Inhalation is driven primarily by the diaphragm. When the diaphragm contracts, the ribcage expands and the contents of the abdomen are moved downward. This results in a larger thoracic volume. As the pressure in the chest falls, air moves into the conducting zone.

Elastic (Power) Speed: In football the elastic speed is often related to a powerful action, this would be something like a driving shot when the leg is thumped through the ball after being swung backwards then forwards as quick and hard as possible.
